摘　　要：软件可信性是保证软件质量的重要因素.文章以研究组件化软件系统的可信性为目的,以组件自身的属性作为出发点,结合组件的权重和不同组合模式,建立相应的软件系统可信度量模型.根据组件自身的各种属性,建立单个组件的可信性度量.结合组件的权重和组件的各种组合方式,分别建立相应系统的可信性度量模型.通过理论验证,这些模型满足单调性、非负性、凝聚性、敏感性和替代性等代数性质,更有利于开发人员及用户对软件可信性进行分析和度量.列举相关案例对可信性度量模型进行验证.Software trustworthiness is an important factor to ensure software quality.The component design method has great influence on software trustworthiness and software quality.In this paper,based on the attri. butes of the components,and combining the weight and different combination modes of components,the soft. ware system trustworthiness measurement models were established.First,according to the various attributes of the component,the trustworthiness of a single component was computed.Then,combining the weight of compo. nent and various combinations of components,the trustworthiness measurement models of the system were proposed.It is proved that these models meet the algebraic properties of monotonicity,non-negativity,acceler. ation,sensitivity,and substitution,which are more conducive to the developers and users to analyze and mea. sure the trustworthiness of the software.Finally,some cases are listed to verify the reasonability of trustworthi. ness measurement model.
